Definitions

  • the invention relates to a ski binding according to the first part (preamble) of claim 1 or 2.
  • the bracket consists of a single, multi-curved and loop-shaped spring wire, which is pivotally arranged with its two free end regions in the pivot bearings of a retaining bracket having a locking pin.
  • the two lower leg sections of the bracket serve to support the front and side edge of the sole of a cross-country shoe inserted into the binding.
  • the section of the retaining bracket that is looped back towards the two bearing points can be fixed to a catch by means of a lock designed as a lever.
  • the swivel part is mounted on a ski-fixed bracket so as to be pivotable about an axis that is independent of the pivot bearings. This axis is formed by two hinge points of the ski-fixed bracket.
  • the swivel angle of the swivel part is limited by a stop and the swiveling takes place against the force of a separate spring (plastic spring). Furthermore, the swivel part is extended in the direction of the cross-country shoe and carries in this end region the pivot bearing for the retaining bracket, which can be fixed in the closed position of the binding by means of a spring-loaded lock. Thus, the transverse axis for the pivoting of the bracket relative to the pivot part now runs in the rear region of the bracket.
  • the spring-loaded lock for fixing the retaining bracket in the closed position of the binding has a pawl which can be pivoted against the force of a spring about an axis formed by a bolt and running parallel to the longitudinal axis of the binding.
  • the bolt is mounted on a separately attached to the swivel extension and an additional, firmly connected to the swivel part, projecting rag.
  • DE-A1-30 23 774 discloses a ski binding which is similar to the basic structure of the CH-A-541.979-like ski binding treated in series.
  • An advantage of this known solution compared to the state of the art already discussed is that the pivoting part, referred to in that document as the web, stands obliquely backwards for the ski boot in the open position of the binding in the direction of getting in.
  • the locking pins provided on the pivoting part, into which the openings of the sole extension of the shoe are to be inserted project normally to the base of the pivoting part, so that these openings have to be introduced while simultaneously pivoting down the shoe and pivoting part.
  • the design and arrangement of the bracket is similar to the solution already dealt with according to CH-A-541.979, with the difference that a loop-like area of the bracket is guided in an elongated hole.
  • AT-B-357.081 already discloses a binding in which the component acting as a retaining bracket is designed in the manner of a shell, this retaining bracket being separated from the pivoting part carrying the locking pins and a releasable lock fixing the retaining bracket to the pivoting part in the closed position of the binding.
  • this known solution is cumbersome in that cross-country skiing takes place about a pivot axis provided on the side surfaces of the ski, so that the entire binding continuously performs a tilting movement during cross-country skiing about this pivot axis.
  • Such an arrangement is not practical because of the risk of the swivel bearing being worn out in the ski, but the continuous tilting movement during cross-country skiing cannot be described as satisfactory either. This tilting movement can lead to damage to the top of the ski both in the front and in the rear area of the binding.
  • the ski binding known from AT-B-351.983, in which the shoe to be fastened has a relatively extended sole extension, which is provided with a flexible zone lying directly in front of the shoe, which allows the heel to be raised.
  • the attachment point of the sole extension lies in front of the flexible zone and is therefore relatively far from the shoe.
  • the end area of the sole extension is connected to the ski as firmly as possible by inserting the sole extension into a ski-proof tip pocket and inserting it into it, e.g. by screwing.
  • the invention has now set itself the task of ensuring a comfortable entry into the binding (step-in) with a ski binding of the type mentioned, without having to make a laborious threading into the upwardly projecting locking pin with the sole extension of the shoe.
  • those disadvantages are to be eliminated, which result from an arrangement of the retaining bracket opposite to the movement of getting in and out (e.g. according to CH-A-541.779) or from tilting movements while running (cf.AT-B-357.081).
  • running around a defined axis should take place, so that the configuration of bending zones in the shoe sole (as is present, for example, in DE-A1-30 45 701) can be avoided entirely.
  • the sole extension should also be kept as short as possible.
  • the set goal is achieved according to the invention by the second part (by the characterizing features) of claim 1 or 2.
  • the features of claim 1 provide a resilient support for the swivel plate and compared to the known prior art according to CH-A-518.107 Bracket with the cross-country shoe formed unit for running in the sense of CH-A-541.979, but without its disadvantages. Characterized in that a second spring holding bracket and swivel part loads in the sense of a spread apart, the binding is always ready for boarding in its position released by the releasable lock.
  • the shell-like design of the bracket also promotes safe entry with the shoe and creates the basis for automatic locking when the binding is closed.
  • the solution according to claim 2 enables the production of a variant of the invention, in which the pivot axis for the pivot part can be formed from its own flexible material.
  • the features of claim 3 serve for a particularly full support of the bracket in the sliding phase and thus for a low construction for both configurations.
  • the subject of claim 4 simplifies the structure of the ski binding in the first embodiment.
  • an advantageous embodiment and arrangement of the lock and for both configurations ensures their favorable cooperation with the bracket. Due to the design of the pawl according to claim 6, in addition to a secure mounting of the binding in the closed position, an easy exit is also ensured.
  • the features of claim 7 in turn provide a simple structure of the binding. since the pawl is simultaneously loaded by the spring acting on the pivoting part. However, if you want to load the resilient lock independently of the spring force that occurs when running, then the use of a further (third) spring is expedient according to the features of claim 8.
  • the features of claim 9 serve for a particularly simple possibility of supporting the springs, the spring arrangement itself being characterized by the features of claim 10.
  • the pawl-side spring section is designed as a hollow body.
  • the approach of the swivel part in grooves can be inserted into a recess provided in the base plate-side section of the spring element.
  • the pawl-side section of the spring element is made of the material of the full body and is of stepped construction. In all embodiments, this ensures that the pawl-side section of the spring element is supported on the attachment of the swivel part, while maintaining a resilient support.
  • the measure of claim 16 has the advantage that it pulls the sole extension into the ski binding, thereby improving the hold of the ski boot in the ski binding.
  • the subject matter of claim 17 ensures that the retaining bracket is held by the spring or springs during the boarding process at a fixed angle to the base plate, which always enables safe boarding in a defined position.
  • the thickness of the approach of the pivot member is independent of the spring element, and it can be made thicker or thinner without having to change the dimensions of the spring element.
  • the subject matter of claim 19 enables a central attack of the swivel part on the spring element without the thickness of the extension of the swivel part being influenced.
  • claim 21 facilitates free deformation of the detent spring.
  • the measure of claim 24 changes the ratio of the spring force of the detent spring to that of the main spring in the first phase of the compression.
  • the direction of evasion of the detent spring is precisely determined during compression.
  • the detent spring is simultaneously used as a cover, which prevents snow and dirt from penetrating into the interior of the ski binding.
  • the measure of claim 28 favors both the boarding process and the boarding process.
  • the measure of claim 29 has the effect that the distance of the front of the locking pin along which a retraction of the sole extension takes place is additionally extended.
  • the shoe is secured against relative movement relative to the retaining bracket on its underside and by the features of claim 32 on its top.
  • the subject-matter of claim 33 has the advantage that the arrangement of two grooves on the one hand increases the safety of the sole extension of the shoe against twisting relative to the retaining bracket, but on the other hand, unacceptable material weaknesses do not occur in the retaining bracket or in the sole extension.
  • a ski binding 1 according to the invention makes it possible to attach a boot 22 which is only provided with a relatively short sole extension 24, in which through openings 23 are provided for receiving locking pins 7 of the ski binding 1 (see FIGS. 1 and 4 or 2 , 3 and 5).

Description

Die Erfindung betrifft eine Skibindung gemäß dem ersten Teil (Oberbegriff) des Patentanspruches 1 oder 2.The invention relates to a ski binding according to the first part (preamble) of claim 1 or 2.

Eine Skibindung dieser Art ist in der CH-A-518.107 geoffenbart. Bei dieser bekannten Lösung . besteht der Haltebügel aus einem einzigen, mehrfach gebogenen und schleifenartig gestalteten Federdraht, welcher mit seinen beiden freien Endbereichen in Drehlagern eines Verriegelungszapfen aufweisenden Haltebügels schwenkbar angeordnet ist. Die beiden unteren Schenkelabschnitte des Haltebügels dienen zur Abstützung des vorderen und seitlichen Schuhsohlenrandes eines in die Bindung eingesetzten Langlaufschuhs. Der schleifenartig in Richtung zu den beiden Lagerstellen zurückgeführte Abschnitt des Haltebügels kann mittels einer als Hebel ausgebildeten Sperre an einer Raste festgelegt werden. Der Schwenkteil ist an einer skifesten Halterung um eine von den Drehlagern unabhängige Achse schwenkbar gelagert. Diese Achse ist durch zwei Scharnierstellen der skifesten Halterung gebildet.A ski binding of this kind is disclosed in CH-A-518.107. With this known solution. the bracket consists of a single, multi-curved and loop-shaped spring wire, which is pivotally arranged with its two free end regions in the pivot bearings of a retaining bracket having a locking pin. The two lower leg sections of the bracket serve to support the front and side edge of the sole of a cross-country shoe inserted into the binding. The section of the retaining bracket that is looped back towards the two bearing points can be fixed to a catch by means of a lock designed as a lever. The swivel part is mounted on a ski-fixed bracket so as to be pivotable about an axis that is independent of the pivot bearings. This axis is formed by two hinge points of the ski-fixed bracket.

Ein Vorteil dieser bekannten Lösung liegt darin, daß das Hochschwenken des Langslaufschuhs um die horizontale Querachse des Schwenkteils vor sich geht. Dadurch wird eine Biegebeanspruchung im Ballenbereich, wie dies bei bekannten herkömmlichen Langlaufschuhen der Fall war, vermieden. Allerdings ist dann auch keine Federung gegeben, die den Langlaufschuh in Richtung zum Ski hin für die Gleitphase zurückführen würde. Nachteilig bei der bekannten Lösung ist weiters, daß der Langlaufschuh in diese Bindung in herkömmlicher Art einzusetzen ist, d.h. bei geöffnetem Haltebügel die Sohlenverlängerung des Langlaufschuhs in die Verriegelungszapfen mit den dort vorhandenen Öffnungen von oben her einzufädeln ist, anschließend wird der Haltebügel auf den Schuhsohlenrand niedergeschwenkt und mittels des Hebels gegen die Eigenfederung des Haltebügels von Hand aus festgespannt. Der Umstand, daß diese Skibindung bei Torsionsbeanspruchungen durch Freigabe des Haltebügels eine Art Sicherheit gewährleisten soll, ändert an der vorher beschriebenen umständlichen Handhabung nichts.An advantage of this known solution is that the cross-country shoe is pivoted up about the horizontal transverse axis of the pivoting part. This avoids bending stress in the ball area, as was the case with known conventional cross-country shoes. However, there is then no suspension that would lead the cross-country ski back towards the ski for the sliding phase. Another disadvantage of the known solution is that the cross-country shoe is to be inserted into this binding in a conventional manner, i.e. When the retaining bracket is open, the sole extension of the cross-country shoe is to be threaded into the locking pin with the openings there from above, then the retaining bracket is swung down onto the edge of the sole of the shoe and tightened by hand against the self-springing of the retaining bracket. The fact that this ski binding is intended to ensure a kind of security in the event of torsion stresses by releasing the retaining bracket does not change the previously described cumbersome handling.

Bei dem zugehörigen Zusatzpatent nach der CH-A-541.979 ist der Schwenkwinkel des Schwenkteiles durch einen Anschlag begrenzt und das Verschwenken erfolgt gegen die Kraft einer gesonderten Feder (Kunststoff-Feder). Weiters ist der Schwenkteil in Richtung zum Langlaufschuh hin verlängert und trägt in diesem Endbereich die Drehlager für den Haltebügel, der in der Schließstellung der Bindung mittels einer gefederten Sperre festlegbar ist. Somit verläuft die Querachse für die Verschwenkung des Haltebügels relativ zum Schwenkteil nunmehr im hinteren Bereich des Haltebügels. Diese Anordnung weist gegen die Richtung einer natürlichen Festlegung des Langlaufschuhs an bzw. in der Skibindung, da die dem Schuh benachbarten Bereiche der Sohlenverlängerung früher mit dem Haltebügel in Berührung kommen als deren nach vorn weisende Bereiche. Wie aus Fig. 2 dieser Druckschrift erkennbar, trägt der vordere Sohlenrand zur Halterung des Schuhs in der Bindung gar nicht bei.In the associated additional patent according to CH-A-541.979, the swivel angle of the swivel part is limited by a stop and the swiveling takes place against the force of a separate spring (plastic spring). Furthermore, the swivel part is extended in the direction of the cross-country shoe and carries in this end region the pivot bearing for the retaining bracket, which can be fixed in the closed position of the binding by means of a spring-loaded lock. Thus, the transverse axis for the pivoting of the bracket relative to the pivot part now runs in the rear region of the bracket. This arrangement points against the direction of a natural fixing of the cross-country ski boot or in the ski binding, since the regions of the sole extension adjacent to the boot come into contact with the holding bracket earlier than their forward-facing regions. As can be seen from Fig. 2 of this document, the front edge of the sole does not contribute to holding the shoe in the binding.

Die geferderte Sperre zur Festlegung des Haltebügels in der Schließstellung der Bindung weist eine Klinke auf, die um eine parallel zur Längsachse der Bindung verlaufende, durch einen Bolzen gebildete Achse gegen die Kraft einer Feder verschwenkbar ist. Der Bolzen ist dabei an einem am Schwenkteil gesondert befestigten Fortsatz und einem zusätzlichen, mit dem Schwenkteil fest verbundenen, hochragenden Lappen gelagert. Dadurch ergeben sich jedoch zusätzliche Bauteile, die das Gesamtgewicht der Bindung erhöhen und zufolge der Anordnung auch keine selbsttägige Handhabung gewährleisten. Auch das Aussteigen aus der Bindung mit dem Langlaufschuh ist insoferne umständlich, als nach Öffnen der Sperre zwecks Freigabe für die Bewegung des Schuhs der Haltebügel vorerst in Richtung zum Langlaufschuh hin verschwenkt, sodann die Schuhsohlenverlängerung aus den Verriegelungszapfen vertikal nach oben herausgehoben werden muß. Erst dann kann der Langslaufschuh aus der Bindung entfernt werden.The spring-loaded lock for fixing the retaining bracket in the closed position of the binding has a pawl which can be pivoted against the force of a spring about an axis formed by a bolt and running parallel to the longitudinal axis of the binding. The bolt is mounted on a separately attached to the swivel extension and an additional, firmly connected to the swivel part, projecting rag. However, this results in additional components which increase the total weight of the binding and, due to the arrangement, also do not ensure automatic handling. Also getting out of the binding with the cross-country shoe is cumbersome in that when the lock is opened to release the movement of the shoe, the retaining bracket is initially pivoted in the direction of the cross-country shoe, so that the shoe sole extension must be lifted vertically upward out of the locking pin. Only then can the cross-country shoe be removed from the binding.

Infolge des gattungsmäßigen Unterschiedes hinsichtlich der Anordnung des Haltebügels relativ zum Schwenkteil liegt diese bekannte Lösung vom Anmeldungsgegenstand weiter entfernt, als der berücksichtigte Stand der Technik nach der CH-A-518.107.As a result of the generic difference with regard to the arrangement of the holding bracket relative to the swivel part, this known solution is further away from the subject of the application than the considered prior art according to CH-A-518.107.

Der Vollständigkeit halber sei noch die DE-A1-30 45 701 genannt, bei der zwar ein Mechanismus zum Festhalten der Sohlenverlängerung vorgesehen ist, der Länglaufschritt hingegen in herkömmlicher Art, nämlich um einen beigsamen Bereich der Sohle, vor sich geht. Dieser Unterschied allein bestimmt aber eine andere Gattung von Langlauf-Bindung-Schuh-Systemen als der Gegenstand der Erfindung.For the sake of completeness, DE-A1-30 45 701 should also be mentioned, in which although a mechanism for holding the sole extension is provided, the cross-country step, on the other hand, takes place in a conventional manner, namely around a flexible area of the sole. This difference alone determines a different type of cross-country binding-shoe system than the object of the invention.

Bei einer weiters bekannten Lösung nach der EP-A1-0095 400 werden zwar ebenfalls zwei Federn verwendet, von denen die eine den Widerstand beim Langlaufen und die andere die Beaufschlagung der lösbaren Sperre bewirkt, jedoch wird bei dieser bekannten Lösung der Langlaufschuh mittels zweier Nuten, die in der Sohlenverlängerung vorgesehen sind, mit zwei hochstenenden Rippen der Bindung in Eingriff gebracht, wobei das Einsetzen des Skischuhs im wesentlichen in der Vertikalebene zu erfolgen hat. Der Aufnahmeteil, welcher gleichzeitig als eine federbeaufschlagte Sperre wirksam ist, verläuft zu dieser Bewegungsrichtung unter einem Winkel. Das Einsetzen des Skischuhs fordert somit auch bei dieser Ausgestaltung eine nicht unerhebliche Geschicklichkeit, wobei durch die einstückige Ausgestaltung von Schwenkteil und lösbare Sperre den bei Massenartikeln erforderlichen Toleranzen unerwünschte niedrige Grenzen gesetzt sind. Auch Anhäufung von Schne, Eis und Schmutz kann das einwandfreie Schießen dieser Bindung bei eingesetztem Schuh negativ beeinträchtigen, oder aber muß der Längläufer nach jeder Unterbrechung die Bindung und Schuch gründlich reinigen.In a further known solution according to EP-A1-0095 400, two springs are also used, one of which provides resistance when cross-country skiing and the other causes the releasable lock to be acted upon, but in this known solution the cross-country shoe is made by means of two grooves, which are provided in the sole extension, brought into engagement with two uppermost ribs of the binding, the insertion of the ski boot essentially taking place in the vertical plane. The receiving part, which also acts as a spring-loaded lock, runs at an angle to this direction of movement. The use of the ski boot therefore requires considerable skill, even with this configuration, the undesirable low limits being set for the tolerances required for mass-produced items through the one-piece configuration of the pivoting part and the releasable lock. Accumulation of snow, ice and dirt can also negatively affect the correct shooting of this binding when the shoe is inserted pregnant, or the long-distance runner must thoroughly clean the binding and scarf after each interruption.

Eine hinsichtlicht des prinzipiellen Aufbaus des bereihts behandelten CH-A-541.979 ähnliche Skibindung ist in der DE-A1-30 23 774 geoffenbart. Ein Vorteil dieser bekannten Lösung liegt gegenüber dem bereits behandelten Stand der Technik darin, daß der in jener Druckschrift als Steg bezeichnete Schwenkteil in der Offenstellung der Bindung in Richtung zum Einsteigen für den Skischuh schräg nach hinten steht. Allerdings ragen dabei die am Skhwenkteil vorgesehenen Verriegelungszapfen, in welche die Öffnungen der Sohlenverlängerung des Schuhs einzuführen sind, normal zur Basis des Schwenkteils, so daß diese Öffnungen beim gleichzeitigen Niederschwenken von Schuh und Schwenkteil eingeführt werden müssen. Die Ausgestaltung und Anordnung des Haltebügels ist ähnlich der bereits behandelten Lösung nach der CH-A-541.979, mit dem Unterschied, daß ein schleifenartiger Bereich des Haltebügels in einem Langloch geführt ist.DE-A1-30 23 774 discloses a ski binding which is similar to the basic structure of the CH-A-541.979-like ski binding treated in series. An advantage of this known solution compared to the state of the art already discussed is that the pivoting part, referred to in that document as the web, stands obliquely backwards for the ski boot in the open position of the binding in the direction of getting in. However, the locking pins provided on the pivoting part, into which the openings of the sole extension of the shoe are to be inserted, project normally to the base of the pivoting part, so that these openings have to be introduced while simultaneously pivoting down the shoe and pivoting part. The design and arrangement of the bracket is similar to the solution already dealt with according to CH-A-541.979, with the difference that a loop-like area of the bracket is guided in an elongated hole.

Auch beim Aussteigen mit dem Schuh aus dieser Bindung muß die Sohlenverlängerung des Schuhs erst aus den Verriegelungszapfen entfernt werden und nur anschließend kann man mit dem Schuh zur Gänze aussteigen.Even when getting out of this binding with the shoe, the sole extension of the shoe must first be removed from the locking pin and only then can the shoe be completely removed.

Die AT-B-357.081 offenbart zwar schon eine Bindung, bei der der als Haltebügel wirksame Bauteil schalenartig ausgebildet ist, wobei dieser Haltebügel vom die Verriegelungszapfen tragenden Schwenkteil getrennt ist und in Schließstellung der Bindung eine lösbare Sperre den Haltebügel am Schwenkteil festlegt. Jedoch ist diese bekannte Lösung insoferne umständlich, als das Langlaufen um eine an den Seitenflächen des Ski vorgesehene Schwenkachse erfolgt, so daß die gesamte Bindung während des Langlaufens um diese Schwenkachse über die Lagerwangen dauernd eine Kippbewegung durchführt. Eine solche Anordnung ist allein aufgrund der Gefahr der Ausleierung der Drehlagerung im Ski praxisfremd, aber auch die dauernde Kippbewegung während des Langlaufens kann nicht als zufriedenstellend bezeichnet werden. Dabei kann diese Kippbewegung sowohl im vorderen als auch im hinteren Bereich der Bindung zu einer Beschädigung der Skioberseite führen.AT-B-357.081 already discloses a binding in which the component acting as a retaining bracket is designed in the manner of a shell, this retaining bracket being separated from the pivoting part carrying the locking pins and a releasable lock fixing the retaining bracket to the pivoting part in the closed position of the binding. However, this known solution is cumbersome in that cross-country skiing takes place about a pivot axis provided on the side surfaces of the ski, so that the entire binding continuously performs a tilting movement during cross-country skiing about this pivot axis. Such an arrangement is not practical because of the risk of the swivel bearing being worn out in the ski, but the continuous tilting movement during cross-country skiing cannot be described as satisfactory either. This tilting movement can lead to damage to the top of the ski both in the front and in the rear area of the binding.

Bei einer anderen, lediglich hinsichtlich der Zeichnung veröffentlichten bekannten Lösung nach der FI-A1-1924/73 (Vgl. Fig. 4-6) ist zwar ein Einstieg mit dem Skischuh ähnlich wie bei der bereits behandelten DE-A1-30 23 774 (Step-in), jedoch vollzieht sich das Laufen in herkömmlicher Art durch Deformation der Schuhsohle im Ballenbereich.In another known solution according to FI-A1-1924 / 73, which is only published with regard to the drawing (see Fig. 4-6), an entry with the ski boot is similar to that of DE-A1-30 23 774 (already discussed). Step-in), however, running takes place in a conventional way by deforming the sole of the shoe in the ball area.

Lediglich der Vollständigkeit halber sei auf die aus der AT-B-351.983 bekannte Skibindung hingewiesen, bei welcher der zu befestigende Schuh eine relativ ausgedehnte Sohlenverlangerung aufweist, die mit einer unmittelbar vor dem Schuh liegenden flexiblen Zone versehen ist, welche ein Anheben der Ferse zuläßt. Die Befestigungsstelle der Sohlenverlängerung liegt vor der flexiblen Zone und ist somit relativ weit vom Schuh enfernt. Um dennoch eine sichere Führung des schuhs zue erzielen, wird der Endbereich der Sohlenverlängerung möglichst fest mit dem Ski verbunden, indem die Sohlenverlängerung in eine skifeste Spitzentasche eingeschoben und in dieser, z.B. durch Verschrauben, festgehalten wird.Merely for the sake of completeness, reference is made to the ski binding known from AT-B-351.983, in which the shoe to be fastened has a relatively extended sole extension, which is provided with a flexible zone lying directly in front of the shoe, which allows the heel to be raised. The attachment point of the sole extension lies in front of the flexible zone and is therefore relatively far from the shoe. In order to achieve safe guidance of the shoe, the end area of the sole extension is connected to the ski as firmly as possible by inserting the sole extension into a ski-proof tip pocket and inserting it into it, e.g. by screwing.

Die Erfindung hat sich nun die Aufgabe gestellt, bei einer Skibindung der eingangs genannten Art ein bequemes Einsteigen in die Bindung (Step-in) zu gewährleisten, ohne dabei mit der Sohlenverlängerung des Schuhs ein umständliches Einfädeln in die nach oben ragenden Verriegelungszapfen vornehmen zu müssen. Dabei sollen auch jene Nachteile beseitigt werden, die zufolge einer der Bewegung des Ein- und Aussteigens entgegengesetzten Anordnung des Haltebügels (z.B. nach der CH-A-541.779) oder durch Kippbewegungen beim Laufen (vgl. AT-B-357.081) entstehen. Des weiteren soll das Laufen um eine definierte Achse erfolgen, so daß die Ausgestaltung von Biegezonen in der Schuhsohle (wie sie beispielsweise in der DE-A1-30 45 701 vorhanden ist) zur Gänze vermieden werden kann. Dabei soll auch die Sohlenverlängerung tunlichst kurz gehalten werden.The invention has now set itself the task of ensuring a comfortable entry into the binding (step-in) with a ski binding of the type mentioned, without having to make a laborious threading into the upwardly projecting locking pin with the sole extension of the shoe. Thereby also those disadvantages are to be eliminated, which result from an arrangement of the retaining bracket opposite to the movement of getting in and out (e.g. according to CH-A-541.779) or from tilting movements while running (cf.AT-B-357.081). Furthermore, running around a defined axis should take place, so that the configuration of bending zones in the shoe sole (as is present, for example, in DE-A1-30 45 701) can be avoided entirely. The sole extension should also be kept as short as possible.

Erreicht wird das gesetzte Ziel erfindungsgemäß durch den zweiten Teil (durch die kennzeichhenen Merkmale) des Anspruches 1 oder 2. Durch die Merkmale des Anspruches 1 wird gegenüber dem bekannten Stand der Technik nach der CH-A-518.107 eine federnde Abstützung für die aus Schwenkplatte und Haltebügel mit dem Langlaufschuh gebildete Einheit für das Laufen im Sinne der CH-A-541.979, jedoch ohne deren Nachteile, geschaffen. Dadurch, daß eine zweite Feder Haltebügel und Schwenkteil im Sinne eines Auseinanderspreizens belastet, steht die Bindung in ihrer von der lösbaren Sperre freigegebenen Lage immer einsteigbereit. Die schalenartige Ausgestaltung des Haltebügels begünstigt zusätzlich das sicher Einsteigen mit dem Schuh und schafft die Grundlage für eine sebsttätige Verriegelung beim Schließen der Bindung.The set goal is achieved according to the invention by the second part (by the characterizing features) of claim 1 or 2. The features of claim 1 provide a resilient support for the swivel plate and compared to the known prior art according to CH-A-518.107 Bracket with the cross-country shoe formed unit for running in the sense of CH-A-541.979, but without its disadvantages. Characterized in that a second spring holding bracket and swivel part loads in the sense of a spread apart, the binding is always ready for boarding in its position released by the releasable lock. The shell-like design of the bracket also promotes safe entry with the shoe and creates the basis for automatic locking when the binding is closed.

Die Lösung nach Patentanspruch 2 ermöglicht die Herstellung einer Variante der Erfindung, bei der die Schwenkachse für den Schwenkteil aus dem eigenen, biegsamen Material gebildet werden kann.The solution according to claim 2 enables the production of a variant of the invention, in which the pivot axis for the pivot part can be formed from its own flexible material.

Die in den Unteransprüchen enthaltenen Mäßnahmen sind auf die beiden Ausgestaltungen der Erfindung nach den Ansprüchen 1 oder 2 gemäß ihren unmittelbaren oder mittelbaren Rückbeziehungen anwendbar.The measures contained in the subclaims are applicable to the two embodiments of the invention according to claims 1 or 2 according to their direct or indirect relationships.

Für eine besonders satte Auflage des Haltebügels in der Gleitphase und somit für eine niedrige Bauweise dienen für beide Ausgestaltungen die Merkmale des Anspruches 3. Durch den Gegenstand des Anspruches 4 wird bei der ersten Ausgestaltung der Aufbau der Skibindung vereinfacht. Nach den Merkmalen des Anspruches 5 wird für beide Ausgestaltungen eine vorteilhafte Ausgestaltung und Anordnung der Sperre sowie deren günstige Zusammenarbeit mit dem Haltebügel gewährleistet. Durch die Ausbildung der Klinke nach Anspruch 6 ist neben einer sicheren Halterung der Bindung in der Schließstellung auch ein leichtes Aussteigen gewährleistet.The features of claim 3 serve for a particularly full support of the bracket in the sliding phase and thus for a low construction for both configurations. The subject of claim 4 simplifies the structure of the ski binding in the first embodiment. According to the features of claim 5, an advantageous embodiment and arrangement of the lock and for both configurations ensures their favorable cooperation with the bracket. Due to the design of the pawl according to claim 6, in addition to a secure mounting of the binding in the closed position, an easy exit is also ensured.

Durch die Merkmale des Anspruches 7 ist wiederum ein einfacher Aufbau der Bindung gegeben, . da die Klinke gleichzeitig von der den Schwenkteil beaufschlagenden Feder belastet ist. Will man jedoch die federnde Sperre unabhängig von der beim Laufen auftretenden Federkraft belasten, so ist nach den Merkmalen des Anspruches 8 die Verwendung einer weiteren (dritten) Feder zweckmäßig. Für eine besonders einfache Abstützmöglichkeit der Federn dienen die Merkmale des Anspruches 9, wobei die Federanordnung selbst durch die Merkmale des Anspruches 10 gekennzeichnet ist.The features of claim 7 in turn provide a simple structure of the binding. since the pawl is simultaneously loaded by the spring acting on the pivoting part. However, if you want to load the resilient lock independently of the spring force that occurs when running, then the use of a further (third) spring is expedient according to the features of claim 8. The features of claim 9 serve for a particularly simple possibility of supporting the springs, the spring arrangement itself being characterized by the features of claim 10.

Die Verwendung von unterchiedlich starken Federn für die das Laufen bestimmende Feder und die Klinke belastende Feder dient ein einstückig ausgebildetes Federelement, welches gemäß den Merkmalen des Anspruches 11 zwei Abschnitte mit unterschiedlichen Eigenschaften (Federcharakteristiken) aufweist.The use of springs of different strengths for the spring determining the running and the spring loading the pawl serves a one-piece spring element which, according to the features of claim 11, has two sections with different properties (spring characteristics).

Für die konstruktive Ausgestaltung des einstükkig ausgebildeten Federelementes bieten sich mehrere Lösungen an. Nach Anspruch 12 ist der klinkenseitige Federabschnitt als hohlkörper ausgebildet.There are several solutions for the structural design of the one-piece spring element. According to claim 12, the pawl-side spring section is designed as a hollow body.

Nach Anspruch 13 ist der Ansatz des Schwenkteiles in Nuten, nach Anspruch 14, hingegen in eine im grundplattenseitigen Abschnitt des Federelementes vorgesehene Aussparung einführbar. Nach Anspruch 15 ist der klinkenseitige Abschnitt des Federelementes aus dem Material des Vollkörpers hergestellt und abgesetzt ausgebildet. In allen Ausführungsformem ist hierdurch eine Abstützung des klinkenseitigen Abschnittes des Federelementes am Ansatz des Schwenkteiles-unter Beibehaltung einer federnden Abstützung-gewährleistet.According to claim 13, the approach of the swivel part in grooves, according to claim 14, on the other hand, can be inserted into a recess provided in the base plate-side section of the spring element. According to claim 15, the pawl-side section of the spring element is made of the material of the full body and is of stepped construction. In all embodiments, this ensures that the pawl-side section of the spring element is supported on the attachment of the swivel part, while maintaining a resilient support.

Die Maßnahme des Anspruches 16 bringt den Vorteil mit sich, daß durch sie die Sohlenverlängerung in die Skibindung hineingezogen wird, wodurch der Halt des Skischuhs in der Skibindung verbessert wird.The measure of claim 16 has the advantage that it pulls the sole extension into the ski binding, thereby improving the hold of the ski boot in the ski binding.

Durch den Gegenstand des Anspruches 17 wird sichergestellt, daß der Haltebügel von der bzw. den Federn beim Einsteigvorgang in einem festgehaltenen Winkel zur Grundplatte gehalten wird, was ein sicheres Einsteigen immer in einer definierten Lage möglich macht.The subject matter of claim 17 ensures that the retaining bracket is held by the spring or springs during the boarding process at a fixed angle to the base plate, which always enables safe boarding in a defined position.

Durch die Maßnahme des Anspruches 18 wird die Dicke des Ansatzes des Schwenkteiles vom Federelement unabhängig, und er kann dicker oder dünner ausgebilde werden, ohne daß dab die Abmessungen des Federelementes geändert werden müssen.By the measure of claim 18, the thickness of the approach of the pivot member is independent of the spring element, and it can be made thicker or thinner without having to change the dimensions of the spring element.

Der Gegenstand des Anspruches 19 ermöglicht einen mittigen Angriff des Schwenkteiles am Federelement, ohne daß dabei die Dicke des Ansatzes des Schwenkteiles beeinflußt wird.The subject matter of claim 19 enables a central attack of the swivel part on the spring element without the thickness of the extension of the swivel part being influenced.

Durch die Merkmale der Ansprüche 20 und 22 wird das Trägheitsmoment des Querschnittes der Rastfeder vergrößert, ohne daß dabei die Abstützfläche für den Ansatz des Schwenkteiles wesentlich verkleinert wird.Due to the features of claims 20 and 22, the moment of inertia of the cross section of the detent spring is increased without the support surface for the attachment of the pivoting part being significantly reduced.

Der Gegenstand des Anspruches 21 erleichtert eine freie Deformation der Rastfeder.The subject matter of claim 21 facilitates free deformation of the detent spring.

Im Anspruch 23 wird eine vorteilhafte weitere Ausgestaltung des Erfindungsgegenstandes unter Schutz gestellt.In claim 23, an advantageous further embodiment of the subject of the invention is protected.

Durch die Maßnahme des Anspruches 24 wird das Verhältnis der Federkraft der Rastfeder zu der der Hauptfeder in der ersten Phase der Kompression stärker verändert.The measure of claim 24 changes the ratio of the spring force of the detent spring to that of the main spring in the first phase of the compression.

Durch die Ausbildung gemäß Anspruch 25 wird die Ausweichrichtung der Rastfeder bei einer Kompression genau festgelegt.Through the design according to claim 25, the direction of evasion of the detent spring is precisely determined during compression.

Im übrigen wird bei den Ausführungen gemäß den Ansprüchen 19,20,22,23 und 24 die Rastfeder gleichzeitig als Abdeckung verwendet, die ein Eindringen von Schnee und Schmutz in das Innere der Skibindung verhindert.Incidentally, in the embodiments according to claims 19, 20, 22, 23 and 24, the detent spring is simultaneously used as a cover, which prevents snow and dirt from penetrating into the interior of the ski binding.

Durch die Merkmale des Anspruches 26 wird einerseits eine Vereinfachung des Einsteigvorganges des Skischuhs und anderseits eine Verbesserung der Halterung des Skischuhs herbeigeführt.The features of claim 26, on the one hand, simplify the entry process of the ski boot and, on the other hand, improve the mounting of the ski boot.

In der Praxis hat es sich als besonders vorteilhaft erwiesen, wenn auch die Merkmale des Anspruches 27 bei dem Verriegelungszapfen verwirklicht sind.In practice, it has proven to be particularly advantageous if the features of claim 27 are also realized in the locking pin.

Durch die Maßnahme des Anspruches 28 wird sowohl der Einsteigvorgang als auch derAussteigvorgang begünstigt.The measure of claim 28 favors both the boarding process and the boarding process.

Die Maßnahme des Anspruches 29 bringt den Effekt mit sich, daß die Strecke der Vorderseite der Verriegelungszapfen, längs der ein Einziehen der Sohlenverlängerung stattfindet, zusätzlich verlängert wird.The measure of claim 29 has the effect that the distance of the front of the locking pin along which a retraction of the sole extension takes place is additionally extended.

Durch den Gegenstand des Anspruches 30, welcher sich auf beide Ausgestaltungen der Erfindung bezieht, ist bei eingesetzten Skischuh eine Relativbewegung zwischen dem Haltebügel und der Sohlenverlängerung auch dann ausgeschlossen, wenn zwischen den keilförmig verlaufenden seitlichen Begrenzungsflächen der Sohlenverlängerung und den zugehörigen Flächen des Haltebügels ein Spiel vorhanden sein sollte bzw. wenn die Aufnahmebohrungen für die Verriegelungszapfen in der Sohlenverlängerung ausgeleiert sein sollten.Due to the subject matter of claim 30, which relates to both embodiments of the invention, a relative movement between the holding bracket and the sole extension is also ruled out when the ski boot is inserted even if there is a game between the wedge-shaped lateral boundary surfaces of the sole extension and the associated surfaces of the holding bracket should be or if the mounting holes for the locking pins in the sole extension should be worn out.

Durch die Maßnahme des Anspruches 31 wird der Schuh gegen eine Relativbewegung gegenüber dem Haltebügel an seiner Unterseite und durch die Merkmale des Anspruches 32 an seiner Oberseite abgesichert.By the measure of claim 31, the shoe is secured against relative movement relative to the retaining bracket on its underside and by the features of claim 32 on its top.

Schließlich hat der Gegenstand des Anspruches 33 den Vorteil, daß durch die Anordnung von zwei Nuten einerseits die Sicherheit der Sohlenverlängerung des Schuhs gegen Verdrehen gegenüber dem Haltebügel erhöht wird, anderseits aber weder im Haltebügel noch in der Sohlenverlängerung umzumutbare Materialschwächungen auftreten.Finally, the subject-matter of claim 33 has the advantage that the arrangement of two grooves on the one hand increases the safety of the sole extension of the shoe against twisting relative to the retaining bracket, but on the other hand, unacceptable material weaknesses do not occur in the retaining bracket or in the sole extension.

Eine erfindungsgemäße Skibindung 1 ermöglicht es, einen Schuh 22 zu befestigen, der lediglich mit einer relativ kurzen Sohlenverlängerung 24 versehen ist, in welcher durchgehende Öffnungen 23 zur Aufnahme von Verriegelungszapfen 7 der Skibindung 1 vorgesehen sind (vgl. Fig. 1 und 4 bzw. 2, 3 und 5).A ski binding 1 according to the invention makes it possible to attach a boot 22 which is only provided with a relatively short sole extension 24, in which through openings 23 are provided for receiving locking pins 7 of the ski binding 1 (see FIGS. 1 and 4 or 2 , 3 and 5).

Die Skibindung 1 zur Befestigung eines derartigen Schuhs 22 ist auf einer Grundplatte 2 angeordnet, die in an sich bekannter Weise, beispielsweise mittels hier nur angedeuteter Schrauben 17, an der Oberseite eines nicht dargestellten Ski befestigt ist. Die Skibindung 1 weist einen schalenartig ausgebildeten Haltebügel 5 (mit einem Boden 5a und mit zwei seitlichen Führungen 5b auf, welche letzteren den Rand der Sohlenverlängerung 24 des eingesetzten Schuhs 22 übergreifen und diesen damit in vertikaler Richtung fixieren. Zur Verhinderung von Längs- und Drehbewegungen des Schuhs 22 wirkt ein den Verriegelungszapfen 7 tragender Schwenkteil 4 in einer insbesondere aus Fig. 2 und 3 ersichtlichen Weise mit dem Haltebügel 5 zusammen. Der Schwenkteil 4 liegt unter der Wirkung einer ersten Feder 11, die sich über ein Widerlager 16 gleichzeitig an einem vertikalen Fortsatz 4b des Schwenkteiles 4 sowie an einer in der weiteren Folge noch zu beschreibenden und als Sperre wirksamen Klinke 9 abstützt, am skifesten Grundkörper 2 an, welcher ein horizontale Querachse 3 trägt. Sowohl der Haltebügel 5 als auch der Schwenkteil 4 sind auf der horizontalen Querachse 3 gelagert, wobei eine als Schenkelfeder ausgebildete zweite Feder 6 den Haltebügel 5 in die aus Fig. 2 hervorgehende Lage nach oben verschwenkt, soferne die noch zu beschreibende Klinke 9 dies nicht verhindert.The ski binding 1 for fastening such a boot 22 is arranged on a base plate 2 which is fastened in a manner known per se, for example by means of screws 17 only indicated here, to the top of a ski (not shown). The ski binding 1 has a shell-like holding bracket 5 (with a base 5a and with two lateral guides 5b, which grip the latter over the edge of the sole extension 24 of the inserted shoe 22 and thus fix it in the vertical direction. To prevent longitudinal and rotational movements of the Shoes 22, a pivoting part 4 carrying the locking pin 7 cooperates with the retaining bracket 5 in a manner which can be seen in particular in Figures 2 and 3. The pivoting part 4 is under the action of a first spring 11 which at the same time rests on a vertical extension via an abutment 16 4b of the swivel part 4 and on a pawl 9, which will be described in the following and act as a lock, on the ski-fixed base body 2, which carries a horizontal transverse axis 3. Both the holding bracket 5 and the swivel part 4 are on the horizontal transverse axis 3 mounted, with a second spring 6 designed as a leg spring, the brace The bow 5 is pivoted upwards into the position shown in FIG. 2, provided that the pawl 9 to be described does not prevent this.

Beim Einsteigen in die in Fig. 2 dargestellte geöffnete Skibindung 1 wird der Schuh 22 schräg in den Haltebügel 5 eingeschoben, wobei die in den Haltebügel 5 hineinragende Klinke 9 durch eine entsprechende Ausnehmung 24a in der Sohlenverlängerung 24 freigestellt wird. Darauf hin wird der Schuh 22 gemeinsam mit dem Haltebügel 5 nach unten in die Stellung gemäß Fig. 3 verschwenkt durch die Verriegelungszapfen (7) festgehalten, welche die durchgehenden Öffnungen 23 der Sohlenverlängerung 24 durchdringen. Die Klinke 9, welche um eine Achse 8 verschwenkbar ist, gleitet dabei über den Rand des Haltebügels 5 und wird schließlich in dessen Rastnut 5d verrastet. Damit ist die Skibindung 1 geschlossen und der Haltebügel 5 sowie Schwenkteil 4, die zusammen die Sohlenverlängerung 24 festhalten, sind gemeinsam gegen die Wirkung der ersten Feder 11 um die Querachse 3 nach oben verschwenkbar.When entering the open ski binding 1 shown in FIG. 2, the shoe 22 is inserted obliquely into the holding bracket 5, the pawl 9 projecting into the holding bracket 5 being released by a corresponding recess 24a in the sole extension 24. The shoe 22 is then pivoted together with the holding bracket 5 downward into the position shown in FIG. 3 by the locking pins (7) which penetrate the through openings 23 of the sole extension 24. The pawl 9, which is pivotable about an axis 8, slides over the edge of the bracket 5 and is finally locked in the locking groove 5d. The ski binding 1 is thus closed and the holding bracket 5 and swivel part 4, which together hold the sole extension 24, can together be pivoted upward about the transverse axis 3 against the action of the first spring 11.

Zum öffnen der Skibindung 1 ist es lediglich notwendig, auf eine Mulde 10 der Klinke 9, beispielsweise mittels eines Skistockes, eine geringfügige Kraft auszuüben und dadurch die Klinke 9 aus der Rastnut 5d des Haltebügels 5 herauszuschwenken. Anschließend wird der haltebügel 5 so weit nach oben verschwenkt, bis die Verriegelungszapfen 7 nicht mehr in die Öffnungen 23 des Schuhs 22 ragen.To open the ski binding 1, it is only necessary to exert a slight force on a recess 10 of the pawl 9, for example by means of a ski pole, and thereby to pivot the pawl 9 out of the locking groove 5d of the retaining bracket 5. The retaining bracket 5 is then pivoted upwards until the locking pins 7 no longer protrude into the openings 23 of the shoe 22.

Wie insbesondere Fig. 5 zeigt, ist es möglich, die beschriebene Skibindung 1 ganz nahe am Ski zu halten, indem der Boden 5a des Haltebügels 5 mit einer Ausnehmung 15 versehen wird, welche einen dem Verriegelungszapfen 7 benachbarten, plattenförmigen Bereich 4a des Schwenkteiles 4 im geschlossen Zustand der Skibindung 1 aufnimmt. Weder die Schrauben 17, welche den Grundkörper 2 am Ski festhalten, noch der Schwenkteil 4 bedingen damit eine Distanzierung des Schuhs 22 vom Ski, welche das Ausmaß der Dicke des Bodenteiles des Grundkörpers 2 und des plattenförmigen Bereiches 4a des Schwenkteils 4 überschreitet.As shown in FIG. 5 in particular, it is possible to keep the described ski binding 1 very close to the ski by providing the bottom 5a of the holding bracket 5 with a recess 15 which forms a plate-shaped region 4a of the pivoting part 4 adjacent to the locking pin 7 in the closed state of ski binding 1 picks up. Neither the screws 17, which hold the base body 2 to the ski, nor the swivel part 4 therefore require the boot 22 to be distanced from the ski, which exceeds the extent of the thickness of the base part of the base body 2 and of the plate-shaped region 4a of the swivel part 4.

Während beim Ausführungsbeispiel nach den Fig. 1 bis 5 sowohl die gemeinsame Verschwenkung von Haltebügel 5 und Schwenkteil 4 wie auch deren Ralativbewegung um die gleiche Querachse 3 erfolgt, ist beim Ausführungsbeispiel der Skibindung 1' nach Fig. 6 eine Trennung dieser beiden Schwenkachsen vorgesehen. Hiezu ist der Schwenkteil 4' aus elastischem Material ausgebildet und mit einer als eine (ideelle) Querachse 14' wirksamen Biegekante versehen, welche ein Hochschwenken gegenüber seinem mit Schrau- . ben 21 am Ski befestigten vorderen Rand erlaubt. Die Konstruktion nach Fig. 6 ist gegenüber jener nach Fig. 1 bis 5 insoferne einfacher, als der Schwenkteil 4' auch die Funktion des Grundkörpers 2 übernimmt, anderseits ist eine Biegekante für Dauerbeanspruchungen weniger geeignet als die gesonderte Querachse 3 gemäß Fig. 1 bis 5. Die Ausführung nach Fig. 6 wird daher vorwiegend dann gewählt werden, wenn Wert auf eine besonders einfache Konstruktion gelegt wird.While in the embodiment of FIGS. 1 to 5, both the joint pivoting of the bracket 5 and pivoting part 4 and their ralative movement by the same que axis 3 takes place, a separation of these two pivot axes is provided in the embodiment of the ski binding 1 'according to FIG. 6. For this purpose, the swivel part 4 'is made of elastic material and is provided with a bending edge which acts as an (ideal) transverse axis 14' and which swivels upwards relative to its with screw. ben 21 allowed to the front edge attached to the ski. The construction according to FIG. 6 is simpler compared to that according to FIGS. 1 to 5 insofar as the swivel part 4 'also takes over the function of the base body 2, on the other hand a bending edge is less suitable for permanent stresses than the separate transverse axis 3 according to FIGS. 1 to 5 6 will therefore mainly be chosen if value is placed on a particularly simple construction.

Die Fig. 7, 8, 9, 15 und 22 zeigen verschiedene Ausgestaltungen von Skibindungen 100, 100', 100", 200 bzw. 300, mit denen der anhand der Fig. 1-5 beschriebene Schuh 22 Verwendung finden kann. Die einzelnen Bereiche dieses Schuhs werden in der folgenden Beschreibung nicht ausführlich beziffert. Des weiteren wird der Aufbau und die Wirkungsweise nur in Verbindung mit der ersten Ausführungsform nach Fig. 7 eingehend erörtert.7, 8, 9, 15 and 22 show different configurations of ski bindings 100, 100 ', 100 ", 200 and 300, respectively, with which the boot 22 described with reference to FIGS. 1-5 can be used. The individual areas This shoe is not detailed in the following description, and the structure and mode of operation are only discussed in detail in connection with the first embodiment according to FIG.

In der Fig. 7 ist mit 100 die Skibindung in ihrer Gesamtheit bezeichnet. Sie besitzt eine Grundplatte 102, welche im Bereich ihrer beiden Längsseiten hochgezogene Ränder 102a aufweist. In diesen Rändern 102a ist eine Querachse 103 abgestützt, auf der sowohl ein Schwenkteil 104 als auch ein Haltebügel 105 gelagert ist. Der Haltebügel 105 besitzt einen Boden 105a und zwei seitliche Führungen 105b für eine Sohlenverlängerung des Schuhs. Außerdem ist der Haltebügel 105 mit einem Steg 105c versehen, der eine Rastnut 105d aufweist. Weiters befindet sich auf der Querachse 103 eine Schenkelfeder 106, welche bestrebt ist, den Haltebügel 105 entgegen dem Uhrzeigersinn nach oben zu verschwenken.In FIG. 7, 100 denotes the ski binding in its entirety. It has a base plate 102, which has raised edges 102a in the region of its two long sides. A transverse axis 103 is supported in these edges 102a, on which both a swivel part 104 and a holding bracket 105 are mounted. The holding bracket 105 has a bottom 105a and two lateral guides 105b for an extension of the sole of the shoe. In addition, the bracket 105 is provided with a web 105c, which has a locking groove 105d. Furthermore, there is a leg spring 106 on the transverse axis 103, which strives to pivot the retaining bracket 105 counterclockwise upwards.

Der Schwenkteil 104 ist etwa als Winkelhebel ausgebildet. Er trägt an seinem zum Skiende hin gerichteten Hebelarm 104a zwei nach oben gerichtete Verriegelungszapfen 107, die zum Eingriff in entsprechende Löcher der Sohlenverlängerung des Schuhs bestimmt sind. Im anderen Hebelarm 104b ist eine Achse 108 befestigt, auf der eine Klinke 109 schwenkbar gelagert ist. Auch die Klinke 109 ist als zweiarmiger Hebel ausgebildet, wobei der eine Hebelarm 109a eine Rastnase trägt, wogegen der andere Hebelarm 109b eine Mulde 110 zum Eingriff der Spitze eines Skistokkesaufweist.The swivel part 104 is designed approximately as an angle lever. On its lever arm 104a, which is directed towards the end of the ski, it carries two locking pins 107, which are directed upwards and are intended for engagement in corresponding holes in the sole extension of the boot. In the other lever arm 104b, an axle 108 is fastened, on which a pawl 109 is pivotally mounted. The pawl 109 is also designed as a two-armed lever, one lever arm 109a carrying a latching lug, whereas the other lever arm 109b has a recess 110 for engaging the tip of a ski rack.

An einem Widerlager 102b der Grundplatte 102 ist eine als Schraubendruckfeder gestaltete erste Feder 111 abgestützt, deren oberes Ende an einem Ansatz 104c des Schwenkteiles 104 anliegt. Mit diesem Ansatz 104c steht weiters das untere Ende einer als Druckfeder gestalteten weiteren (dritten) Feder 112 in Berührung, welche dazu dient, die Klinke 109 in ihre Sperrlage zu drücken.A first spring 111 designed as a helical compression spring is supported on an abutment 102b of the base plate 102, the upper end of which rests on a shoulder 104c of the swivel part 104. This approach 104c furthermore contacts the lower end of a further (third) spring 112 designed as a compression spring, which serves to press the pawl 109 into its locked position.

Bevor der Skiläufer mit seinem Schuh in die Skibindung 100 einsteigt, nimmt diese die in Fig. 7 dargestellte Lage ein, in der der Haltebügel 105 mit der Grundplatte 102 einen Winkel zwischen 30 und 45° einschließt, welcher das Einsteigen erleichtert und die Gefahr eines Davongleitens des Ski beim Einstieg verhindern soll. Der Schuh 22 wird daher längs des Bodens 105a des Haltebügels 105 gegen den Steg 105c hin verschoben, bis die Öffnungen 23 der Sohlenverlängerung 24 des Schuhs 22 (vgl. Fig. 4) über die Verriegelungszapfen 107 zu liegen kommen. Danach wird der Schuh 22 niedergedrückt. Dies hat aber zufolge, daß der Haltebügel 105 gegen die Kraft der zweiten Feder 106 um die Querachse 103 verschwenkt wird. Bei dieser Verschwenkung des Haltebügels 105 gleitet der Hebelarm 109a der Klinke 109 über den Steg 105c des Haltebügels 105, bis die Nase des Hebelarmes 109a in der Rastnut 105d zu liegen kommt.Before the skier climbs into the ski binding 100 with his shoe, this assumes the position shown in FIG. 7, in which the holding bracket 105 forms an angle between 30 and 45 ° with the base plate 102, which makes it easier to get in and the risk of slipping away prevent the ski from entering. The shoe 22 is therefore displaced along the bottom 105a of the holding bracket 105 against the web 105c until the openings 23 of the sole extension 24 of the shoe 22 (see FIG. 4) come to rest over the locking pins 107. Then the shoe 22 is depressed. However, this has the consequence that the holding bracket 105 is pivoted against the force of the second spring 106 about the transverse axis 103. During this pivoting of the holding bracket 105, the lever arm 109a of the pawl 109 slides over the web 105c of the holding bracket 105 until the nose of the lever arm 109a comes to rest in the latching groove 105d.

Die Abmessungen des Steges 105c des Haltebügels 105 und des Hebelarmes 109a der Klinke 109 sind so gewählt, daß während einer Schwenkbewegung der andere Hebelarm 109b gegen den Ansatz 104c des Schwenkteiles 104 gedrückt wird und dabei die weitere (dritte) Feder 112 voll komprimiert. Dadurch wird erreicht, daß beim Einsteigen in die Skibindung 100 mit dem Schuh 22 der Haltebügel 105 durch die Klinke 109, wie oben beschrieben, sicher verrastet wird.The dimensions of the web 105c of the holding bracket 105 and the lever arm 109a of the pawl 109 are selected such that the other lever arm 109b is pressed against the shoulder 104c of the pivoting part 104 during a pivoting movement and the further (third) spring 112 is fully compressed in the process. It is thereby achieved that when stepping into the ski binding 100 with the shoe 22, the holding bracket 105 is securely locked by the pawl 109, as described above.

Während eines Langlaufschrittes wird der Schwenkteil 104, der nun über die Klinke 109 mit dem Haltebügel 105 fest verbunden ist, gegen die Kraft der ersten Feder 111 entgegen dem Uhrzeigersinn verschwenkt. Die erste Feder 111 wird dabei etwas zusammengedrückt. Unter dem Einfluß dieser Feder 111 wird die Einheit von Schwenkteil 104 und Haltebügel 105 am Ende eines Langlaufschrittes wieder im Uhrzeigersinn zurückgeschwenkt.During a cross-country skiing step, the swivel part 104, which is now firmly connected to the holding bracket 105 via the pawl 109, is swiveled counterclockwise against the force of the first spring 111. The first spring 111 is compressed somewhat. Under the influence of this spring 111, the unit of pivoting part 104 and retaining bracket 105 is pivoted back clockwise at the end of a cross-country skiing step.

Soll die Skibindung 100 vom Schuh 22 gelöst werden, so wird die Spitze eines Skistockes in die Mulde 110 eingesetzt und die Klinke 109 entgegen dem Uhrzeigersinn verschwenkt. Dies hat aber zufolge, daß die Rastnase des Hebelarmes 109a der Klinke 109 die Rastnut 105d im Haltebügel 105 verläßt, wodurch die Verbindung von Schwenkteil 104 und Haltebügel 105 gelöst wird. Der Haltebügel 105 kann sich daher unter dem Einfluß der zweiten Feder 106 in die in Fig. 7 dargestellte Lage bewegen, in der die Verriegelungszapfen 107 die Öffnungen 23 der Sohlenverlängerung 24 des Schuhs 22 bereits verlassen haben. Der Schuh 22 kann nun aus der Skibindung 100 herausgezogen werden.If the ski binding 100 is to be released from the boot 22, the tip of a ski pole is inserted into the depression 110 and the pawl 109 is pivoted counterclockwise. However, this has the consequence that the locking lug of the lever arm 109a of the pawl 109 leaves the locking groove 105d in the holding bracket 105, as a result of which the connection between the pivoting part 104 and the holding bracket 105 is released. The retaining bracket 105 can therefore move under the influence of the second spring 106 into the position shown in FIG. 7, in which the locking pins 107 have already left the openings 23 of the sole extension 24 of the shoe 22. The shoe 22 can now be pulled out of the ski binding 100.

Die Skibindung 100' gemäß Fig. 8 ist der zuletzt beschriebenen. Ausführung sehr ähnlich. Die unterscheidet sich von ihr lediglich dadurch, daß die erste Feder 111' nicht als Schraubendruckfeder, sondern als ein elastischer Block aus Kunststoff oder Gummi zwischen einem Widerlager 102'b der Grundplatte 102' und einem Ansatz 104'c eines Schwenkteiles 104' vorgesehen ist. Die übrigen Elemente entsprechen denen der vorangehenden Ausführung, wobei zur Unterscheidung die entsprechenden Bezugsziffern jeweils mit einem Strich versehen sind. Auch die Funktion dieser Skibindung 100' ist der der vorangehenden Ausführung analog.8 is the last described. Very similar design. The only difference from it is that the first spring 111 'is not provided as a helical compression spring, but rather as an elastic block made of plastic or rubber between an abutment 102'b of the base plate 102' and an extension 104'c of a pivoting part 104 '. The remaining elements correspond to those of the previous embodiment, the respective reference numbers being provided with a dash to distinguish them. Also the The function of this ski binding 100 'is analogous to that of the previous embodiment.

Die Skibindung 100" gemäß Fig. 9 unterscheidet sich von den beiden vorhergehenden vor allem dadurch, daß anstelle von zwei Federn, nämlich der gesonderten ersten und weiteren (dritten) Federn, ein einstückig ausgebildetes Federelement 111" aus Kunststoff oder Gummi vorgesehen ist, welches durch einen Ansatz 104"c des Schwenkteiles 104" in zwei Abschnitte unterteilt ist, von denen der eine Abschnitt 111 "a zwischen dem Widerlager 102"b der Grundplatte 102" und dem Ansatz 104"c des Schwenkteiles 104" und der andere Anschnitt 111 "b zwischen dem Ansatz 104"c des Schwenkteiles 104" und dem Hebel 109"b der Klinke 109" liegt.The ski binding 100 "according to FIG. 9 differs from the two previous ones mainly in that instead of two springs, namely the separate first and further (third) springs, a one-piece spring element 111" made of plastic or rubber is provided, which is characterized by a shoulder 104 "c of the pivoting part 104" is divided into two sections, one section 111 "a between the abutment 102" b of the base plate 102 "and the shoulder 104" c of the pivoting part 104 "and the other gate 111" b between the shoulder 104 "c of the pivoting part 104" and the lever 109 "b of the pawl 109".

Der zuletzt genannte Abschnitt 111 "b besitzt einen kleineren Querschnitt als der zuerst genannte Abschnitt 111 "a, weiters hat das Federelement 111" einen Fortsatz 111"g, der den Ansatz 104"c des Schwenkteiles 104" übergreift.The last-mentioned section 111 "b has a smaller cross-section than the first-mentioned section 111" a, furthermore the spring element 111 "has an extension 111" g which engages over the shoulder 104 "c of the swivel part 104".

Ein weiterer Unterschied liegt darin, daß die Zapfen 107" einen rechteckigen Querschnitt aufweisen, wobei ihre Vorderseite mit dem Hebelarm 104"a des Schwenkteiles 104" der Skibindung einen spitzen Winkel a einschließt.Another difference lies in the fact that the pins 107 "have a rectangular cross-section, their front including an acute angle a with the lever arm 104" a of the pivoting part 104 "of the ski binding.

Die übrigen Elemente entsprechen denen der vorhergehenden Ausführungen und sind zur Unterscheidung mit zwei Strichen versehen.The other elements correspond to those of the previous explanations and have two lines to distinguish them.

In den Fig. 10 bis 14 sind verschiedene Ausführungen von Federelementen 111"'―111"""' wiedergegeben. Bei allen Ausführungen ist der Abschnitt zwischen dem Widerlager der Grundplatte und dem Ansatz des Schwenkteiles als Vollkörper ausgebildet. Diese Federelemente können, bei entsprechender Ausgestaltung jener Bauteile, mit denen sie zusammenwirken, wahlweise anstelle des Federelementes 111" nach Fig. 9 eingesetzt werden.10 to 14 different versions of spring elements 111 "'- 111" ""' are shown. In all versions, the section between the abutment of the base plate and the attachment of the swivel part is designed as a solid body. These spring elements can, with a corresponding design of those components with which they interact, optionally be used instead of the spring element 111 "according to FIG. 9.

Bei der Ausführung gemäß Fig. 10 besitzt der als Vollkörper ausgebildete Abschnitt 111"'a des Federelementes 111"' eine rechteckige Aussparung 111"'c, in welche der Ansatz des Schwenkteiles einschiebbar ist. Der zwischen dem Ansatz des Schwenkteils und der Klinke verlaufende Abschnitt 111 "'b des Federelementes ist als Hohlkörper ausgebildet.10, the section 111 "'a of the spring element 111"' 'in the form of a solid body has a rectangular recess 111 "' c into which the attachment of the swivel part can be pushed in. The section running between the attachment of the swivel part and the pawl 111 "'b of the spring element is designed as a hollow body.

Fig. 11 zeigt eine ähliche Ausführung eines Federelementes 111 "", die sich von der Ausführung nach Fig. 10 lediglich dadurch unterscheidet, daß es zwei Nuten 111""d aufweist, in welche ein gabelförmig gestalteter Ansatz des Schwenkgliedes eingreifen kann.Fig. 11 shows a similar embodiment of a spring element 111 "", which differs from the embodiment according to Fig. 10 only in that it has two grooves 111 "" d, in which a fork-shaped projection of the pivot member can engage.

Das Federelement 111 ""' nach den Fig. 12a, b, c zeichnet sich dadurch aus, daß der Abschnitt zwischen dem Ansatz des Schwenkteiles und der Klinke als nach oben ragende mittige Rippe 111 ""'e ausgebilet ist. Ansonsten besitzt auch diese Federelement 111 ""' eine rechteckige Aussparung 111""'c, in welche der Ansatz des Schwenkteils eingeschoben werden kann.The spring element 111 "" 'according to FIGS. 12a, b, c is characterized in that the section between the attachment of the swivel part and the pawl is designed as an upwardly projecting central rib 111 ""' e. Otherwise, this spring element 111 "" 'also has a rectangular recess 111 ""' c, into which the attachment of the swivel part can be inserted.

Die Variante eines Federelementes 111""" gemäb den Fig. 13a, b, c unterscheidet sich von der vorhergehenden dadurch, daß anstelle einer einzigen Rippe zwei seitliche Rippen 111 """f vorhanden sind. Im übrigen ist auch dieses Federelement 111""" mit Nuten 111"""d versehen, die für einen gabelförmig ausgebildeten Ansatz des Schwenkgliedes bestimmt sind.The variant of a spring element 111 "" "according to FIGS. 13a, b, c differs from the previous one in that two lateral ribs 111" "" f are present instead of a single rib. Otherwise, this spring element 111 "" "is also provided with grooves 111" "" d which are intended for a fork-shaped extension of the pivoting member.

In Fig. 14 ist ein Federelement 111"""' dargestellt, bei dem der Abschnitt 111"""'b zwischen dem Ansatz des Schwenkteiles und der Klinke die Form eines in Draufsicht rechteckigen Rahmens aufweist. Ferner besitzt auch das Federelement 111 """' ein rechteckige Aussparung 111"""'c, in welche der Ansatz des Schwenkteiles eingeschoben werden kann.In Fig. 14, a spring element 111 "" "'is shown, in which the section 111" ""' b between the attachment of the pivoting part and the pawl has the shape of a rectangular frame in plan view. Furthermore, the spring element 111 "" "'also has a rectangular recess 111" ""' c, into which the attachment of the swivel part can be inserted.

Die in Fig. 15 mit 200 bezeichnete Skibindung unterscheidet sich von jener nach Fig. 9 vor allem dadurch, daß die beiden seitlichen Führungen 205b des Haltebügels 205 an ihrer Oberseite eine Querwand tragen, welche einen in Silkängsrichtung verlaufenden Schlitz 205f aufweist. Dieser Schlitz 205f dient dazu, eine zuverlässige Einspannung des Schuhs auch dann sicherzustellen, wenn die Öffnungen in der Sohlenverlängerung ausgeleiert wären. Des weiteren unterscheidet sich diese Skibindung 200 von jener nach Fig. 9 in der Ausgestaltung des als dritte (weitere) Feder 211 b wirksamen Abschnittes 211 b des Federelementes 211 vom vorangehenden Federelement 111".The ski binding designated by 200 in FIG. 15 differs from that according to FIG. 9 primarily in that the two lateral guides 205b of the holding bracket 205 carry on their upper side a transverse wall which has a slot 205f running in the longitudinal direction of the silk. This slot 205f serves to ensure reliable clamping of the shoe even if the openings in the sole extension were worn out. Furthermore, this ski binding 200 differs from that according to FIG. 9 in the configuration of the section 211 b of the spring element 211 which acts as a third (further) spring 211 b from the preceding spring element 111 ″.

Der weitere Aufbau und Wirkungsweise der Skibindung 200 entspricht jenem bzw. jener der Skibindung 100", so daß sich ein weiteres Eingehen auf deren Details erübrigt. In der Fig. 15 sind die breits beschriebenen Bauteile mit 200-Ziffern bezeichnet.The further construction and mode of operation of the ski binding 200 corresponds to that or that of the ski binding 100 ", so that there is no need to go into the details thereof. In FIG. 15, the components which have already been described are designated by 200 digits.

Weitere Ausgestaltungen von Federelement 211' bis 211""", die bei entsprechender Ausgestaltung der mit diesem zusammenwirkenden Bauteile anstelle des Federelementes 211 eingesetzt werden können, sind in den Fig. 16-21 dargestellt.Further configurations of spring element 211 'to 211 "" ", which can be used in place of the spring element 211 with a corresponding configuration of the components interacting therewith, are shown in FIGS. 16-21.

Das in den Fig. 16a und 16b dargestellte Federelement 211' unterscheidet sich vom Federelemente 211 dadurch, daß zu beiden Seiten seiner Längsmittelebene Absätze 211 'c angeordnet sind, an denen sich der an seinem Ende gabelförmig ausgebildete Ansatz des Schwenkteiles abstützt. Dadurch wird es möglich, auf das Federelement 211' eine symmetrische Belastung anzuüben.The spring element 211 'shown in FIGS. 16a and 16b differs from the spring elements 211 in that shoulders 211' c are arranged on both sides of its longitudinal center plane, on which the fork-shaped extension of the pivoting part is supported at its end. This makes it possible to apply a symmetrical load to the spring element 211 '.

Das Federelement 211" gemäß Fig. 17 zeichnet sich dadurch aus, daß die Rastfeder 211"b über ihre ganze Länge einen konstanten Querschnitt aufweist und in Form einer von der ersten Feder 211 "a nach oben ragenden Rippe ausgebildet ist.The spring element 211 "according to FIG. 17 is characterized in that the detent spring 211" b has a constant cross section over its entire length and is designed in the form of a rib projecting upwards from the first spring 211 "a.

Nach Fig. 18 ist die weitere (dritte) Feder 211...b in Draufsicht etwa C-förmig ausgebildet. Dadurch wird das Federelement 211"' gegen Abrutschen vom Ansatz des in Fig. 18 nicht dargestellten Schwenkteiles nach vorne und nach den Seiten gesichert.18, the further (third) spring 211 ... b is approximately C-shaped in plan view.
